  1. Thanks for the instructions. I have done this however it only works on a new e-mail. Is there a setting somewhere so that the signature works on replies and fwd e-mails as well?

    1. Hi Matt,

      When you put in your signature, it should also work for replies and forwards. When replying or forwarding an email, you may need to expand the window in order to see your email signature there. If you don’t expand the window, it doesn’t show you the signature.

      Hope that makes sense.

      1. I have added the signature – tried expanding to see if it is there on replies /forwards – it still is not showing.

  2. My jpeg or picture will not show up on my signature in the iOS outlook app. I have copied and paste from my outlook on my pc, but the image will not show. Please advise.

    1. Hi Michael,

      Unfortunately, the Outlook app for both iOS and Android doesn’t support HTML signatures. This means you can only have a plain text email signature (with no images) when you use it.

      1. It’s 2022 and you cant add a HTML picture to your signatures in outlook?…, Good Job!

  3. After creating my signature I sent a test and my signature block is double spaced not single spaced. Us there a way to correct this?

    1. Hi Dot,

      If you’ve installed your signature in Outlook App for iOS, it will convert the signature from HTML to Plain Text. This is because the Outlook App doesn’t support HTML signatures. Sometimes, in the process of converting it from HTML to Plain Text, it will add double spaces in between the signature fields.

      Feel free to send through a few screenshots to us so we can take a look.

      1. Is there a way to change the font at least? I understand that outlook app doesn’t support html text but it always defaults to new time roman. This problem seems fixable and outdated. Please advise, Thanks.

          1. Please update the app to support HTML email signatures, this day and age, this really even be an issue, nor changing the font. Thanks for the prompt attention to this.

          2. Hi MB,

            Unfortunately, we don’t have control over the Outlook App so we cannot update it – although we wish we could! The only company who can update it is Microsoft.

    1. Unfortunately not. Outlook for iOS does not support HTML email signatures at this time and only supports plain text email signatures which means you cannot insert a logo to it.

  4. Just an update for everyone.

    It appears as though Microsoft has enabled the ability to add HTML signatures for the Outlook App for iOS.

    However, when installing the signature, you MUST use the HTML source code of the email signature, not the finished signature itself.

    I’ve updated the installation guide to reflect the changes 🙂

    1. Hi Chris,

      To get the source code of your email signature from Gimmio, click on the “Click Here if you need the HTML source code (advanced).” part in the installation tab.

      Gimmio Email Signature Source Code

  5. Hi Chris,

    Thank you very much for this helpful guide. Unfortunately, I have two issues remaining:

    (1) the html source code messes up the line spacing

    (2) the picture included in the html source code is not properly displayed

    Are there any solutions available to my problems?

    Thanks very much in advance
    Kind regards,

    1. Hi Alex,

      In regards to the source code line spacing, the source code output from Gimmio is minified. This means all the spacing is removed in order to make the code smaller in size so it takes up less space on mail servers when your email is sent. You can “beautify” the source code if you like, which will add the spacing back in by pasting the HTML code here:

      In regards to the picture that is not displayed correctly, would you mind sending a screenshot of the issue to [email protected] so we can take a closer look for you?

      Thanks and speak soon 🙂

  6. I do not see any direction on how to obtain the HTML source code as directed in step 1. Can anyone direct me on this?

    1. Hi Tara,

      When you’ve created your signature in Gimmio, if you head over to the Installation tab, in step 2, click on “Click Here if you need the HTML source code (advanced).” and that will get you the HTML source code.

  7. Update:

    On October 21st, 2019, it appears that Microsoft released an update for the Outlook App for iOS which prevents HTML email signatures from rendering correctly. Instead, installed email signatures will now show as raw HTML code.

    Unfortunately, it looks like HTML email signatures are not able to be used with Outlook App for iOS any longer.

    1. This is a huge disappointment. Are you familiar with any way to format the font in the email signature on the mobile device? I don’t even need pictures.

      1. Hi Matt,

        Unfortunately, it doesn’t look like its possible to format the text at all since it is showing in plain-text format.

      1. Hi Andrew,

        No problems at all, if we find a solution we will be sure to post it up here.

  8. Thank you for the update as to why my HTML signature stopped working today (and now just shows the actual source code text)! I searched everywhere online today to find out if there was a change or if it was my issue. Hoping there will be a fix soon, as the alternative is very unprofessional looking. Thank you!

    1. Hi Melissa,

      It’s definitely very disappointing! We’ve got our fingers crossed hoping it’s only temporary, but we will see.

    1. Hi Gary,

      Yep, it’s quite a disappointment to say the least. Hopefully, Microsoft releases an update to make them work again.

  9. Thank you Gordan for staying on top of this! I too am shocked, disappointed and angry that MS would do this and am hoping this functionality will be restored soon.

    1. Hi Andrew,

      No problems, thats our job! 🙂

      Looks like Microsoft have released an update to fix this issue which is great to see.

  10. The latest update of the Microsoft Outlook IPhone App has fortunately corrected the HTML signature issue.

  11. Hi everybody,
    in the latest update for IOs 4.8.1 it works again!! 🙂
    best regards

  12. Hey folks….I was pleased to find this thread, I have wasted hours trying to get my corp. signature into my iOS Outlook client, which keep reverting back to plain text, and no images. I see from the thread, that MS has finally addressed the HTML support issue in 4.8.1, yet I’m at 4.9.0…and still no luck ??

    Such a crazy thing there must be a solution 🙁


    1. Hi Mike,

      The latest version of Outlook for iOS should support HTML signatures fine. We have tested this from our end here. When you paste your signature into the Outlook app, you have to make sure you paste the HTML code itself as that is the only way the signature will work correctly.

  13. Hi Gordon,

    I`ve recently made my first signature, and it works great from my desktop, but having installed the html code on both my ipad and iphone, the signature works but none of the images display, my profile pic, logo, or any of the social channel icons, all I get is the dreaded red X. The code was downloaded as instructed using google chrome browser, any suggestions please?

    1. Hi Gary,

      That is definitely very strange that the red X shows up in place of the images on the iPad and iPhone. Would you be able to send through a screenshot to [email protected] and we will take a look into it further.

  14. Thanks, but I found a curious thing:
    Added a signature like “BR Susanne sent from mobile” but when creating a new email the signature appears as “BR Susanne sent from mobile [email protected]
    How does it do this unwanted completion of the signature?

    1. Hi Susanne,

      I haven’t actually seen this happen myself, and I’ve just tried to replicate the issue but I don’t seem to be having any luck. So, just to confirm, you entered your email signature in Outlook on iOS as “BR Susanne sent from mobile” but when composing an email, it came up as “BR Susanne sent from mobile [email protected]“? If that’s the case, that is very strange and I’ve never come across this before. I’ll do some research on this.

  15. I have multiple email accounts on my outlook app, is there any way to assign different signatures to different emails ? (Work vs personal)

    1. Hi Seth,

      I don’t believe there is a way to do this. There is only one signature section where you can paste your signature and it is not account-based, it is for the whole app. Meaning, you would need to use the same signature for all of your email accounts in the Outlook app.

  16. Hey Gordan – When I paste the html code into the signature field of the outlook app and go to compose a message from within the app, the signature looks fine before sending the message. However, once I click send, the formatting changes and removes all color from my signature. It looks this way on both a computer and the app and both in the sent email and the received email. Any ideas on why that is happening or how to fix it?

    1. Hi Michael,

      Sometimes a signature may change slightly when it is sent outside of your email client (but only slightly). This is mainly to do with how the receiving mail server treats HTML and also how the mail client renders the HTML when viewing the email. Also, it sounds like your email signature may be converting to plain-text format from your description. This is a setting which is set either on the mail server, or the email client to convert incoming email to plain text format. Might be worth a check.

    2. I have the exact same issue when using office 365. Checked the html and the color tag is being removed by outlook mobile or possibly by Office365/Exchange Online.

      I wish I could understand why this one tag is being removed.

  17. A recent update to iOS Outlook does indeed strip out color tags and other inlined tags. I have tried finding some workarounds such as changing the color tags on nested elements, or using !important, but nothing I have found yet allows you to control color within the inline style attributes.

    Furthermore, non-inlined style tags and css that you would normally have at the head of the signature for support on other platforms are printed as plain text! Outlook keeps regressing in their handling of email signatures, and I have to explain to all my clients what they are doing and why they should switch away from Outlook if they are serious about controlling their content.

  18. Struggling with linked images in html.

    Are they supported or not? I seem to have one image working fine, but then others all fail.

    How hard is it to get a decent branded signature to be accepted from Apple.

  19. I had set up my HTML signature earlier this year and it worked fine (outlook ios app). I accidentally deleted the app last week and need to set it up again.

    This time around, it’s letting me have rich/formatted text but I can’t include an image (our logo). So, I switched back and got the HTML text but for some reason it won’t convert the HTML text. When I send an email it’s just the HTML code.

    Any suggestions on why this is happening?

    1. Hi Adrienne,

      Recently, the Outlook iOS app has been updated by Microsoft, and now you can only use the formatted HTML signature and cannot use the raw HTML code like before. If you’re having problems installing your Gimmio signature and need some assistance, feel free to email us at [email protected] along with some screenshots of the issue and we will help you out.

  20. Hey Gordan,

    Thanks for the helpful article. I can copy and paste a signature into the mobile app and it works with the correct custom colors, but when a coworker does the same thing, the colors are reverted to default. Any suggestions for her?


  21. Any news on this topic? Would really like to add a solid signature from the Outlook iOS app. Including pictures and proper lining.
